euclid-wm is a minimalist tiling window manager for X11. It is designed to allow quick and easy management of numerous windows entirely from easy-to-learn, Vim-like key-bindings. It seeks to do two things in particular: balance the ease of use common among automatic-layout tiling window managers with the flexibility of manual layout window managers, and create a useful way to handle minimized applications.
Lunchbox is a dynamic tiling window manager for X11. It allows windows to be resized by squishing them against the edge of the screen. In a step away from the desktop metaphor, all programs are given a separate workspace and unique arrangement of windows, and any window can become the desktop. It offers an in-built scalable tab replacement called the Title Menu, which allows any window to be swapped with any other window that fits, allowing very fine grained control over the layout of the screen. Finally, although many windows default to tiling, any window can be changed to a Floating mode, which dialog boxes default to.
